Value of some old Mighty Beanz?

Hi, the other day I bought a few Mighty Beanz at a yard sale and I was wondering if anyone knew anything about their value. I think the racetracks are worth about $20 each now (that's what someone on Reddit told me) but I have no idea about the beans. I also got two carrying cases and two balance beam things that were not included in the photo. I was hoping of selling everything for around $40. Am I trying to get too much, or is that a fair price? Also are any of the beans rare or worth anything on their own? Thanks.
